Updated the source tarballs of FisicaLab

Due to a reported problem with the configure script, I updated the source tarball of FisicaLab, included the Mac package. Now the current package is numbered 0.3.5-1. Sorry for the inconveniences.

GNU FisicaLab 0.3.5

I’m glad to announce the release of version 0.3.5 of GNU FisicaLab, this is a feature release. FisicaLab (can be pronounced as PhysicsLab) is an educational application to solve physics problems. Its main objective is let the user to focus in physics concepts, leaving aside the mathematical details

In this version I added a module to handle tables of properties, for the moment this only handle properties for water, but is the base for future modules of thermodynamics and fluids. This took more time that I thought, but now is ready. So now there is a new entry at menu that launch a window where you can calculate the properties of water (saturated, compressed and superheated). I also fix some bugs:

  • Correction of a bug in the module dynamics of points, due to a bad set of equations. This causes that some problems can be solved with some parameters, but not with others.
  • Fixed two problems with the contextual menu of conversions.
  • Minor changes for compatibility with Windows platform. So now FisicaLab have the same behavior on this platform.

This new version is also available as a binary package for GNU/Linux i686 and for GNU/Linux x86_64. There is also a self contained installer for Windows and a source tarball for Mac OS X. I didn’t tested this package since I don’t have a Mac. But in theory should work.

Remember that the documentation is now on line. And in addition I added some videos here. For the moment these are available only in English. And, beforehand, apologies if you don’t understand my English 🙂

I also want to thank the people who have donated to the project. In this version the first time you launch FisicaLab it will display a window with a brief description of FisicaLab where we encourage you to donate to the project.

So enjoy FisicaLab and if you have feedback or find bugs, use the corresponding mailing lists.

gs-emacs 0.1

Well, after play some time with elisp I wrote this package to add a entry called GNUstep to Emacs menu. This entry has three options, two are to make simple App/Tool projects (for beginners). The third is for replace the non English characters to its corresponding code. This is useful for strings and plist files. This three commands can be executed with, respectively: M-x make-app, M-x make-tool y M-x replace-foreign-characters. The image below show the menu:

gnustep-emacs

A Tool project:

gnustep-tool

This package also offers auto-complete for Objective-C and the possibility to open gorm files in dired (load):

gnustep-completion

Compiling and testing a tool:

gnustep-compilation

You can download this package here. Just untar this somewhere and in your .emacs file add something like:

(load-file “/home/user/gs-emacs/gnustep.el”)

See README file if you have installed GNUstep with a non default layout. This is if you need run the GNUstep script.

My intention with this package is help Emacs’ users to learn GNUstep, and make known this wonderful development environment. So I hope this package will be helpful.

GNU FisicaLab is an educational application to learning physics. FisicaLab allows students focus in physics concepts when solving problems, leaving aside the mathematical details. Currently it can solve problems about kinematics of particles, statics of particles and rigid bodies, dynamics of particles (all these in two dimensions) and some problems of heat and calorimetry.

With your support, you will help to expand the range of problems to solve in FisicaLab, in adding new features, in the availability in other languages and in many other things. So help FisicaLab to reach $ 7k at March 31, to give students a chance of get an ethical education with free software. Don’t hesitate and make a donation today
